LAMP.

SPECIFICATION forming part of Letters Patent No. 247,114, datedSeptember 13, 1881. Application filed May 5, 1881. (No model.)

To all whom t't may concern:

Be it known that I, STERNE RUSSELL, of Waterbury, in the county of NewHaven and State of Connecticut, have invented certain new and usefulImprovements in Lamps, of

which the following is a specification.

My improvements are especially applicable to the style of lamps known asstudents lamps, wherein the oil-reservoirs are isolated from thewick-tube and burner, and connected therewith by a laterallyextendingsupplytnbe. Some or all of the improvements are, however, applicable toother styles of lamps.

The improvements consist in a novel means 1 5 whereby the oil reservoirof a lamp may be conveniently filled, and in means whereby the wick-tubewill be prevented from overflowing while the reservoir is being filled.

They also consist in a novel means for adjusting the wick of a lamp.

They also consist in a novel means for fastening an adjustablewick-tube, oil-reservoir, and appurtenances in ditferent positions upona supporting'rod.

In the accompanying drawings, Figure l is a sectional elevation of alamp embodying my improvements, with the chimney-gallery and the baseomitted. Fig. 2 is a horizontal section taken through the oil -reservoiron the plane indicated by the dotted linear ac, Fig. 1.

Fig. 3 is a horizontal section through the oilreservoir on the plane ofthe dotted line 1 3 Fig. 1, looking upward. Fig. 4. is a verticalsection of the wick-tube on an enlarged scale.

55 Fig. 5 is a top View. of the wick-tube ou the same scale. Fig. 6 is aview of the under side of the adjustable slide which fits thesupporting-rod of the lamp and of certain ofitsappurtenances, and Fig. 7is a top view of a catch for retaining said slide in position on thesupporting-rod and of certain of its appurtenances.

, Similar letters of reference designate corresponding parts in all thefigures.

A- designates the oil-reservoir of the lamp.

5 It may be made in the usual cyliudric form, as shown, and of sheetmetal. Atthe upper end it is provided with a filling-chamber, A, andnear the lower end it communicates with a supply-tube, B, extendinglaterally to and communicating with an upright wick tube, G.

The reservoir is permanently connected with the supply-tube B, and maybe considered as v non-detachable" from other parts of the lamp. Thesupply-tube, as shown, is provided with a slide-tube,D,fittingasupporting-rod, E, which may be erected on any suitable base.The reservoir and the wick-tube are arranged on opposite sides of thesupporting-rod E.

The filling-chamber A of the oil-reservoir may-be made of sheet metal,and it is fitted and supported within a flange, a, extending downwardlyinto the reservoir from the top, so as to be free to rotate or turnwithin said flange. In the upright wall of the filling-chamber A is anaperture, b, and atcorresponding elevation in the flange a is anaperture, 0. There is also in this wall of the filling-chamber anaperture, d, (shown at a slightly higher elevation,)and at acorresponding elevation in the flange a is an aperture, 6. These aper-7o tures b c and d e are so arranged that when the filling-chamber isrotated or turned into one position the apertures b and c coincide, andthe apertures d and 0 also coincide, and the former afford a passage foroil from the filling-chamber into the reservoir, while the latter at thesame timeafford a passage for the escape of air from the reservoir. Theapertures d and c are shown as somewhat smalleras well as higher thanthe apertures b and c. The bottom of the filling-chamber preferablyslants downward to the lower part of the aperture b, so that all the oilintroduced into the fillingchamber will flow into the reservoir. Whenthe filling-chamber is rotated or turned in the 8 5 opposite directiontheapertureb is thrown out of coincidence with the aperture 0 and theaperture d is thrown out of coincidence with the aperture e, so that allcommunication between the filling-chamber and the reservoir 0 is out Oh.Pins w on the filling-chamber, acting in conjunction with a lug, z, onthe flange a, limit the rotation or turning of the fillingchamber. I

A designates a cap or plug fitting in an opening in the top of thefilling-chamber A, and provided with pins f, which engage with notches gin the top edge of the filling-chem; ber, so that by rotating or turningthe cap. the. filling-chambermaybe rotated orturned. This we cap isremoved from the filling-chamber when it is desired to fill thereservoir, and oil may be introduced by means of an ordinary oilcan.

F designates a valve for controlling communication between the reservoirA and supply-tube B. As here shown, it is of globular form and adaptedto fit a seat in the end of the supply-tube B and to be moved toward andfrom the end of said tube to close and open the same. It is arranged onthe lower end of a lever, F, which is fulcrumed at h in the reservoir,and whose upper end bears on the face of a cam, G, afiixed to thefillingchamber. TheleverF may swinger vibratein a direction transverseto the length of the reservoir. This cam is rotated or turned with thefillin g-chamber, and hence constitutes arotarydevice for operating thevalve F. When the fillingchamber is rotated or turned so as to cut offcommunication between it and the reservoir through the apertures b c andd c, this cam G withdraws the valve F from its seat in the supply-tubeBby rocking theleverF butwhen the filling-chamber is rotated or turned soas to establish communication between it and the reservoir, the cam Grrecedes and allows a spring, F acting on the lower part of the lever F,to rock the lever so that it will carry the valve F into its seat in thesupply-tube. It will thus be'seen that during the filling ofthereservoir communication between the reservoir and the supply-tube iscut off,but that communication between them is afforded at allothertimes. If the fillin g-chamber A is turned so as just to remove theapertures b (I out of line with the apertures c e, the valve 1 willstill be left closed, owing to the position of the cam Gr with referenceto said apertures.

It is obvious that in lieu of the particular form of cam G and thespring F which I have shown, a cam having a slotted or grooved operatingface corresponding in shape to that of the face of the cam G, andreceiving the upper end of the lever F within it, may be used, and thatthe spring F may then be dispensed with. In such case the cam willoperate the'lever F and valve F in both directions, and the lever willpreferably be made slightly resilient, so that it will yield to allowthe cam to press the valve tightly in its seat after the valve'iscarried into contact with its seat.

The wick-tube O is of cylindric form, and may be constructed in anysuitable manner and of any approved material. It is shown as permanentlysecured to and supported by the supply-tube B. As usual, it is composedof au'inner and outer part, which are united at the bottom, leaving anannular open-topped space between them in communication with thesupply-tube. In this space is contained the wick I, and also. awick-adjusting tube, J, having a screw-threaded exterior, which, whenrotated, operates on the inner surface of the wiclr'to raise or lowerthe wick, the outer part of the wick-tube,by its friction on theexterior of the wick,serving to prevent the latter from turning with thesaid wick-adjusting tube. At the upper end the wick-adjusting tube isprovided with a cross-bar, t, which interlocks with notches j in the topof a tube, K, arranged inside the inner part of the wick-tube, and hencewhen the tube K is turned the wick-adjusting tube is turned also. Thetube K is supported by means of ascrew-rin g, L, screwed into a socketon the bottom of the wick-tube, and embracing between it and the bottomof the wick-tube a flange extending from said tube K. This ring L isprovided at its inner edge with a notch, 70, to allow it to pass over apin, 1, with which the tube K is provided.

M designates a drip-cup, fitting on the lower end of the tube K andretained there by friction. At its upper edge is a notch, m, whichinterlocks with the pin lon the tube K. Hence by turning the drip-cupthe tube K and the wick-adj usting tube J are turned, and the wickraised or lowered.

' On the supply-tube B, near the wick-tube G, I

is a regulator controlling the flow of oil to the wick-tube. It consistsof ach amber, N, mounted on the supply-tube B, and having communicationwith it through an opening, 42. Above this opening the chamber isprovided with transverse plates 0p, which have in them openings q r atremote points. Near the top of the chamber and above its said plates isa hole, 8, establishing communication between the chamber and theexternal atmosphere. When the oil by consumption becomes sufiicientlylowered air enters the chamber and passes or bubbles up into thereservoir and permits more oil to flow to the wick-tube; but while theoil is high in the wick-tube air is precluded from entering thereservoir, and as no oil can then flow from it the overflowing of theoil from the wick-tube is prevented.

On a tube arranged below the slide-tube D is a laterally extending handpiece, 0, by grasping which the said tube and attached parts of the lampmay be raised and lowered. In its under side is a cavity, t, in which ispivoted a lever, P, forming a catch or tooth, so that when its end whichis adjacent to the supporting-rod E is impelled downward by pressingupward its other end it will be disengaged from the rod, and so thatwhen its end which is adjacent to the supporting-rod is impelled upwardit will engage with the rod and sustain the slidet-ube and attachedparts of the lamp. At its outer end this lever P has a finger-piece, P,which may be conveniently manipulated, and conforms to the cavity tinthe hand-piece O. The lever P and fingerpiece P are approximatelyparallel with the hand-piece 0. Between this finger-piece P and thehand-piece O are spiral springs a, which tend to depress the outer endof the lever P and to elevate its inner end, so as to cause it to engagewith the supporting-rod. Hence whenever the finger-piece P is notmanipulated the lever P is in engagementw-ith the supporting-rod, andthe weight of the slidetube and attached parts of the lamp tends to holdit in firm engagement with the supporting-rod.

The spiral springs u may be attached to the finger-piece P, and thelever P may fit between and be steadied by bars 1; in the cavity t ofthe hand-piece O.

It is obvious that the hand piece 0 might be upon the slide-tube D, ifdesirable.

When the slide-tube and the tube or section of tube which is providedwith the hand-piece O are made separate the slide -tube and attachedparts can always be turned around to any position without manipulatingthe handpiece or appurtenances.

It will be seen that by my invention I produce a lamp which may be veryeasily filled, which aflords great convenience for the adjustment of thewick, and for the adjustment of the wick-tube and reservoir to differentelevations.
